Hi, ? I am trying to get OSX working on my laptop for school. After installation I move all IntelHD related .kexts to a backup folder using the USB's Terminal. This way I can boot and get the latest bootloader (Chameleon). Then I use kext installer to install the kexts back. If I connect my screen to VGA output, I get "working" graphics, but very shaky and stretched. If I use internal screen (so no VGA), I get the following error: "Transcript Offline - Buffer Pool Allocate  failed". Laptop screen resolution supports 1600x900. I would like to know how to make it use the laptop screen. ? DSDT, kext edits, any solution I will try. ? I hope I will get the answer, thanks. ? PS: I am on OS X 10.8.4.
